Description

本出願は、2011年7月14日に韓国特許庁に提出された特許出願第10-2011-0069847号の優先権を請求し、本明細書で参照として組み込まれる。
本発明は、バッテリー温度調節システム及びその駆動方法に関するものである。 This application claims the priority of Patent Application No. 10-2011-0069847 filed with the Korean Patent Office on July 14, 2011, and is incorporated herein by reference.
The present invention relates to a battery temperature control system and a driving method thereof.

一般的にハイブリッド及び電気自動車などに使用されているバッテリーは、温度が低くなるほど内部抵抗が急激に増加し、その容量が減少して出力が低下し、特に0℃以下の低温では室温に比べて半分以上、その容量が減少する問題がある。   In general, batteries used in hybrids and electric vehicles have a rapid increase in internal resistance as the temperature decreases, and the capacity decreases and the output decreases, especially at low temperatures below 0 ° C compared to room temperature. There is a problem that the capacity is reduced by more than half.

このような問題を改善するために、従来はバッテリー自体の電源を使用してバッテリーを昇温させる方法を使用した。これは、自動車の走行以外のエネルギー消耗を発生させ、全体的にバッテリーの出力を低下させる結果をもたらす。即ち、バッテリーを昇温させるときに必要なエネルギーをバッテリー自体で調達するため、自動車の走行に必要なエネルギーをさらに消耗する結果を有する。
したがって、別途の電源供給がなくてもバッテリーの出力を低下させずにバッテリーを昇温させる方法に対する研究が必要な実情である。 In order to improve such a problem, conventionally, a method of heating the battery using the power source of the battery itself has been used. This results in energy consumption other than driving the automobile, resulting in a decrease in battery output overall. In other words, since the energy necessary for raising the temperature of the battery is procured by the battery itself, the energy required for driving the automobile is further consumed.
Therefore, there is a need for research on a method for raising the temperature of the battery without lowering the output of the battery even if there is no separate power supply.

本発明は、発熱パッドを含むバッテリー部；前記バッテリー部と連結された導線；及び前記導線を包む電流誘導部を含み、前記電流誘導部は前記発熱パッドと電気的に連結されたことを特徴とするバッテリー温度調節システム及びその駆動方法を提供することとする。

前記バッテリー部200は、モーター部100を駆動させるためのエネルギーを供給する役割をするものであって、複数個のセル220が電気的に連結され、各セル220の間に位置する発熱パッド210を含むことにより、一定の温度を維持することができる。この際、前記セル220は、充・放電が可能な二次電池であることが好ましく、リチウム二次電池であることがさらに好ましいが、これに限定されない。   The battery unit 200 serves to supply energy for driving the motor unit 100. A plurality of cells 220 are electrically connected to each other, and a heating pad 210 positioned between the cells 220 is provided. By including, a constant temperature can be maintained. At this time, the cell 220 is preferably a chargeable / dischargeable secondary battery, more preferably a lithium secondary battery, but is not limited thereto.

具体的には、発熱パッド210は電流誘導部400と電気的に連結されたものであって、電流誘導部400と接合された導線と連結されて、電流誘導部400から誘導電流を供給されることを特徴とする。発熱パッド210は上部に第1の発熱パッドが形成され、下部に第2の発熱パッドが形成され、その間に熱線211が内蔵され、第1の発熱パッドと第2の発熱パッドとの間に熱線211と導線の接合部と導線孔が形成されて導線と連結されるように形成され得る。特に、熱線211は発熱パッド210に内蔵されたものであって、電流誘導部400から発生された誘導電流が供給され、セル220を昇温させる役割をする。熱線の種類は特に限定されず、一般熱線、シリコン熱線、カーボン熱線、特殊カーボン熱線、無磁系熱線等を使用することができる。   Specifically, the heat generating pad 210 is electrically connected to the current induction unit 400 and is connected to a conductive wire joined to the current induction unit 400 so that an induction current is supplied from the current induction unit 400.

前記バッテリー部はパワーツール(Power Tool);電気車(Electric
Vehicle、EV)、ハイブリッド電気車(Hybrid Electric Vehicle、HEV)、及びプラグインハイブリッド電気車(Plug-in Hybrid Electric Vehicle、PHEV)を含む電気車；電気トラック;電気商用車；または電力貯蔵用システムのうち、いずれか一つ以上の中大型デバイスの電源として多様に利用することができる。 The battery part is a power tool; an electric car
Vehicle, EV), hybrid electric vehicle (HEV), and electric vehicle including plug-in hybrid electric vehicle (PHEV); electric truck; electric commercial vehicle; or power storage system Of these, it can be used in various ways as a power source for any one or more medium-sized devices.

前記電流誘導部400は発熱パッド210と電気的に連結されたものであって、発熱パッド210に誘導電流を供給するため、モーター部100とバッテリー部200との間を連結する導線300を包むように形成することができ、一実施例としては導線300をきめ細かく均一に円筒状に長く巻いたソレノイド(solenoid)コイルで構成しても良い。   The current induction unit 400 is electrically connected to the heat generation pad 210, and encloses a conductive wire 300 connecting the motor unit 100 and the battery unit 200 to supply induction current to the heat generation pad 210. As an example, the conductive wire 300 may be formed of a solenoid coil that is finely and uniformly wound in a cylindrical shape.

一般的に電流が流れる導線周囲には磁場が形成されるが、導線を螺旋状に、きめ細かく均一に円筒状に長く巻いて電流を流すと、円筒の外部においては磁場がほぼ0であり、内部においては比較的均一な大きさの磁場が形成される。したがって、前記ソレノイドコイルは電気エネルギーを磁気エネルギーに変えるのでエネルギー変換装置と言うことができ、電流の強さを調節して磁場の強さを調節することができる電磁石になり得るが、この際に発生される誘導電流はソレノイドコイルを形成する物質及び形態に応じて誘導容量が決定され、その値は下記の通りである。
L=μ0n2lA
L=誘導容量
μ0=真空の透磁率
n=単位長さあたりの導線の巻き数
l=ソレノイドコイルの長さ
A=ソレノイドコイルの断面積 Generally, a magnetic field is formed around a conducting wire through which a current flows. However, if a conducting current is wound by winding a conducting wire spirally, finely and uniformly into a cylindrical shape, the magnetic field is almost zero outside the cylinder, and the inside In, a relatively uniform magnetic field is formed. Therefore, the solenoid coil can be called an energy conversion device because it converts electrical energy into magnetic energy, and can be an electromagnet that can adjust the strength of the magnetic field by adjusting the strength of the current. Inductive capacity is determined according to the material and form forming the solenoid coil, and the induced current is as follows.
L = μ 0 n 2 lA
L = Inductive capacity μ 0 = Permeability of vacuum
n = Number of turns of the conductor per unit length
l = Length of solenoid coil
A = sectional area of solenoid coil

この際、ソレノイドコイルは電気伝導性に優れた金属または金属合金からなるが、導電率が5.80×106 mhos/m 以上の金属または金属合金からなることが好ましいが、これに限定されない。このようにソレノイドコイルは、導電率が5.80×106
mhos/m 以上の金属または金属合金であればいずれも使用できるが、本発明の一具体例においては銅からなるソレノイドコイルを使用した。銅は導電率が5.80×107
mhos/m であって電気伝導性に特に優れている。 At this time, the solenoid coil is made of a metal or metal alloy having excellent electrical conductivity, but is preferably made of a metal or metal alloy having a conductivity of 5.80 × 10 6 mhos / m or more, but is not limited thereto. Thus, the solenoid coil has a conductivity of 5.80 × 10 6
Any metal or metal alloy of mhos / m or more can be used, but in one embodiment of the present invention, a solenoid coil made of copper was used. Copper has a conductivity of 5.80 × 10 7
mhos / m, especially excellent in electrical conductivity.

さらに、本発明のバッテリー温度調節システムは前記バッテリー部200の温度を制御するための制御部500をさらに含むことができる。   In addition, the battery temperature control system of the present invention may further include a controller 500 for controlling the temperature of the battery unit 200.

前記制御部500はバッテリー部200のセル220表面の温度をリアルタイムで感知し、基準温度以上になると誘導電流の流れを遮断することにより、バッテリー部200のセル220の温度を適正温度に維持させる役割をする。具体的に、前記制御部500はスイッチ部であっても良く、より具体的に、前記制御部500はソリッド・ステート・リレー(Solid
State Relay)スイッチ部であっても良い。スイッチ部としてソリッド・ステート・リレーを使用することにより、スイッチングの寿命を延ばすことができ、より信頼性のあるスイッチングができる。この際、バッテリー部200の基準温度は20℃ないし30℃の範囲内であることが好ましく、常温(25℃)であることがさらに好ましいが、これに限定されない。バッテリー部200の温度が基準温度以上に上昇するとバッテリーが退化し、むしろ否定的な影響を及ぼすことになるので、バッテリー部200の温度をリアルタイムに感知し、誘導電流の流れを遮断することになる。 The controller 500 senses the temperature of the surface of the cell 220 of the battery unit 200 in real time and blocks the flow of the induced current when the temperature exceeds the reference temperature, thereby maintaining the temperature of the cell 220 of the battery unit 200 at an appropriate temperature do. Specifically, the control unit 500 may be a switch unit, and more specifically, the control unit 500 may be a solid state relay.
(State Relay) switch part may be sufficient. By using a solid state relay as the switch unit, the switching life can be extended and more reliable switching can be performed. At this time, the reference temperature of the battery unit 200 is preferably within a range of 20 ° C. to 30 ° C., more preferably normal temperature (25 ° C.), but is not limited thereto. If the temperature of the battery unit 200 rises above the reference temperature, the battery will degenerate, and rather negative effects will be detected, so the temperature of the battery unit 200 will be sensed in real time and the flow of induced current will be cut off .

さらに、本発明のバッテリー温度調節システムは、従来の通常的な温度調節装置と共に付加的に使用することができる。 Furthermore, the battery temperature control system of the present invention can be additionally used with a conventional temperature control device.

一つの具体例として、本発明のバッテリー温度調節システムは、バッテリー部自体の電源を使用してバッテリー部を昇温させる装置及び別途の電源を使用してバッテリー部を昇温させる装置のうち、少なくとも一つをさらに含むことができる。   As one specific example, the battery temperature control system of the present invention includes at least one of a device for heating a battery unit using a power source of the battery unit itself and a device for heating a battery unit using a separate power source.

(B) generating an induced current in a current induction portion that wraps the conducting wire through the magnetic force formed in the step (a); and (c) generating the heating pad in the step (b). A method for driving a battery temperature control system is provided that includes supplying a induced current.

具体的には、本発明は、(a)モーター部100と発熱パッド210を含むバッテリー部200との間を連結する導線300に電流を発生させてバッテリー部200を充・放電させつつ、導線300周囲に磁気力を形成する段階；(b)前記形成され磁気力を介して前記導線300を包む電流誘導部400内の誘導電流を発生させる段階；及び(c)前記発熱パッド210に、前記(b)の段階において発生した誘導電流を供給する段階を含むバッテリー温度調節システムの駆動方法を提供する。   Specifically, the present invention provides: (a) a conductive wire 300 while charging and discharging the battery unit 200 by generating a current in the conductive wire 300 that connects the motor unit 100 and the battery unit 200 including the heating pad 210.

さらに、本発明のバッテリー温度調節システムの駆動方法は、前記バッテリー部200の温度が基準温度以上に上昇する場合、前記(c)段階において供給された誘導電流を遮断する段階をさらに含むことができる。 Further, the driving method of the battery temperature control system of the present invention may further include a step of cutting off the induced current supplied in the step (c) when the temperature of the battery unit 200 rises above a reference temperature. .

本発明のバッテリー温度調節システムの駆動方法においては、バッテリー部の充・放電過程を介してモーター部100とバッテリー部200との間を連結する導線300に電流を発生させ、これはアンペアの右ねじの法則に従って導線300周囲に磁気力を形成することになる。形成された磁気力を介して導線300を包む電流誘導部400内において誘導電流を発生させる。発生した誘導電流は、バッテリー部200の発熱パッド210に供給され、バッテリー部200を加熱して温度を上げることになる。この際、バッテリー部200の温度をリアルタイムで感知し、基準温度以上に上昇する場合、供給された誘導電流を遮断してバッテリー部200の温度を調節することができる。   In the driving method of the battery temperature control system of the present invention, current is generated in the conductive wire 300 connecting the motor unit 100 and the battery unit 200 through the charging / discharging process of the battery unit, A magnetic force is formed around the conducting wire 300 in accordance with the above law.

The generated induced current is supplied to the heat generating pad 210 of the battery unit 200, and the battery unit 200 is heated to raise the temperature. At this time, if the temperature of the battery unit 200 is sensed in real time and rises above the reference temperature, the supplied current can be cut off to adjust the temperature of the battery unit 200.

この際、バッテリー部200の基準温度は20℃ないし30℃の範囲内であることが好ましく、常温(25℃)であることがさらに好ましいが、これに限定されない。バッテリー部200の温度が基準温度以上に上昇するとバッテリーが退化し、むしろ否定的な影響を及ぼすことになるので、バッテリー部200の温度をリアルタイムに感知し、誘導電流の流れを遮断することになる。   At this time, the reference temperature of the battery unit 200 is preferably within a range of 20 ° C. to 30 ° C., more preferably normal temperature (25 ° C.), but is not limited thereto. If the temperature of the battery unit 200 rises above the reference temperature, the battery will degenerate, and rather negative effects will be detected, so the temperature of the battery unit 200 will be sensed in real time and the flow of induced current will be cut off .

前記したように、本発明に係るバッテリー温度調節システムは、バッテリー部と連結された導線、例えばモーター部100とバッテリー部200との間を連結する導線300を包む電流誘導部400を適用して誘導電流を発生させ、発熱パッド210に誘導電流を供給し、バッテリー部200の温度を上げることによって、外部電源がなくても0℃以下の低温領域において従来のバッテリー自体の電源を使用してバッテリーを昇温させる方法に比べ、最大20％のバッテリー出力向上効果が得られる。 As described above, the battery temperature control system according to the present invention is guided by applying the current induction unit 400 that wraps the conductive wire connected to the battery unit, for example, the conductive wire 300 connecting the motor unit 100 and the battery unit 200. By generating an electric current, supplying an induction current to the heating pad 210, and raising the temperature of the battery unit 200, the battery can be operated using the power supply of the conventional battery itself in a low temperature region of 0 ° C. or less even without an external power supply. Compared to the method of increasing the temperature, the battery output can be improved by up to 20%.
